People expect to be able to run system("dir *.foo") from Perl. But there is no 'dir' executable so to get that to work, Perl needs to actually run: cmd /c "dir *.foo"

So what Perl ran for you was:

C:\> cmd /c "cmd /c systemQuote.bat AA 1" C:\> echo XXXXXXX 1>X_1".log 2>&1 The filename, directory name, or volume label syntax is incorrect.

Which shows that Microsoft has a hard time dealing with quotes in a consistent or even sane and error-free manner. But I tried this:

C:\> cmd /c "cmd /c systemQuote.bat AA 1 " C:\> echo XXXXXXX 1>X_1.log 2>&1 C:\> sleep 5

And putting a trailing space also worked around the problem when running that from Perl.

It used to be that Perl's system() on Windows would try running the command you gave directly first and would only resort to wrapping it in qq(cmd /c "...") if that failed. I think that, over the years, enough edge cases showed up that the details of this technique were changed in order to try to get more "expected behavior" in more cases. If you are interested in details, then check out the source code involved, p5git://win32/win32.c..
